Abstract�� A new approach of GPS integrity based on SINS is studied by means of the Chebyshev-s law of great numbers. The magnitude of pseudoranges can be estimated and that which satellite is in trouble can be determined by using only a Kalman filter. A example is given in the case of step-type pseudorange error. Thesimulation result proves that the new approach is very practical and efficient and the computation load is lower.
